The story of our today’s hero begins in 1987. It is then that the electronic equipment factory in Svetlovodsk (today’s Ukraine) leaves the first calculator Электроника МКУ-1 (Elektronika MKU-1). The device was the result of an idea by officials of the Central Planning Bureau and was designed with a specific purpose in mind – the equipment was to serve high school and college students of the Soviet Union. It would enable them to solve even complex mathematical equations much more quickly and simply.

The great events of the space industry not only capture our attention, but also inspire us to think about the achievements of science and technology.

In the category of retro equipment I usually throw in descriptions of calculators, because they are the biggest part of my collection.

The Elwro 105LN is one of the first office calculators to be produced at the Elwro Wroclaw plant. This device is a direct successor to the 105L model and, in fact, the first mass-produced one since the early 1970s. The design is very interesting both in terms of technical solutions, but also in terms of history, which is not so obvious.

On a cold December morning in the Czech village of Březolupy, a man stops his truck in front of a 17th century castle. He puts on thick gloves, gets out of the truck and opens the tailgate. Then, very carefully, he unloads more crates of heavy equipment and glass.

In my last article on retro equipment, I told you about a pocket calculator manufactured at the Unitra Eltra plant in Bydgoszcz.

During the communist era, pocket calculators were produced by two companies – Wroclaw’s Elwro and Bydgoszcz’s Unitra Eltra.

Since its inception, all digital machines were meant to serve man and help him perform his daily tasks in the office, on the factory floor or at home. However, in order for a machine to be useful, something was needed so that humans could understand it. Nowadays, it is quite normal to have all kinds of screens on which digital systems display information that we can understand, but this was not always the case.
